RUS JR E HU s DOLP RUDO H WILLIAM REINFORCED CONTAINER This invention relates to reinforced containers, and more particularly relates to containers formed from sheet material such as solid or corrugated fiberboard, and reinforced by strips of material attached to the walls of the container.

It is common practice after drying and curing tobacco to package the tobacco in rectangular cases for shipment to plants where the tobacco is utilized. In recent years there has been a noticeable trend towards increased use of corrugated fiberboard containers and a decreased usage of wooden containers for the shipping of tobacco. This trend has been caused by a shortage of skilled labor and by a desire to minimize labor costs in assembling the tobacco case.

However, it has been discovered that tobacco cases formed of even the strongest triple wall fiberboard construction, tend to deform and burst when these tobacco cases are stacked one on top of each other in a warehouse, and allowed to stand in vertical columns for long periods of time. In this regard, tobacco is regularly stored in warehouses for up to 3 years and some warehouses stack the containers in columns up to 12 containers high.

The scope of the problem can be easily seen when it is realized that a standard size tobacco case weighs about 480 pounds when fully loaded. When several such fully loaded cases are stacked one upon each other, as is desirable for efficiently utilizing storage space, the bottom case in the stack is required to support a heavy compressive load.

Thus, while fiberboard wall construction presents desirable economies in costs of assembly, cases formed entirely of fiberboard materials have tended to give less than satisfactory performance when loaded and stored in vertically stacked columns for extended periods of time.

There is also another related, but distinct strength requirement for tobacco cases. Specifically, it is desirable to compress tobacco to pack it compactly into a tobacco container. Generally, a hydraulic press is used to compress the tobacco, and a sleeve which fits inside the sidewalls of the tobacco container, or a corset which fits around the outside of the sidewalls of the tobacco container, is provided to prevent rupture of the sidewalls during the pressing operation. Thus, the design of a reinforced tobacco case desirably makes the case compatible with the corset or sleeve packing apparatus which are designed for conventional fiberboard tobacco cases.

Accordingly, it is a primary object of this invention to provide new and improved containers.

It is a further object of this invention to provide new and improved containers that are capable of being stacked on top of each other without crushing, even when filled with a heavy load.

Another object of this invention is to provide new and improved reinforced containers that can be packed using conventional tobacco packing equipment.

Yet another object of this invention is to provide a new and improved container that may be rapidly assembled and disassembled.

Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

To achieve the foregoing objects andin accordance with the purposes of the invention, as embodied and broadly described herein, the reinforced container of this invention comprises a pair of sidewalls; a pair of end walls; a top wall including a pair of top flaps attached to said end walls; a bottom wall including a pair of bottom flaps attached to said end walls; a pair of vertically extending side cleats attached on an inside surface of each of said walls, each of said side cleats spaced from an end of said sidewalls with the side cleats at each end of the container longitudinally aligned; a pair of bottom cleats attached to and extending across the width of each of said bottom flaps and spaced from said end walls to permit the ends of each of said bottom cleats to abut the lower edge of a pair of longitudinally aligned side cleats; and a pair of top cleats, with one top cleat attached to the inside surface of each of said top flaps and extending across the width of said top flap and spaced from said end walls to permit the ends of each of said top cleats to be seated in abutting contact on a pair oflongitudinally aligned side cleats.

The invention consists in the novel parts, constructions, arrangements, combinations, and improvements shown and described. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate three preferred embodiments of the invention, and, together with the description, serve to explain the principles of the invention.

A plywood-reinforced container for packing tobacco is illustrated in FIGS. l-S. This container, as seen in FIG. 2, is formed from a single foldable blank, generally 20, which includes alternating side panels 22 and end panels 24 with the end panels and side panels separated by fold lines 26. A top flap 28 and a bottom flap 30 are attached on each end panel and are connected to the end panel by fold lines 32 and 34, respectively. A top cleat 36 extends across the inside surface of each top flap and a bottom cleat 38 extends across the bottom surface of each bottom flap 30. The ends of these cleats protrude past the corresponding edges of the flaps a distance which is substantially equal to the thickness of side cleats described below.

The top and bottom cleats are spaced from fold lines 32 and 34 a distance which slightly exceeds the thickness of the top or bottom flap to which they are attached and a distance which corresponds to the spacing of side cleats from the end of the container so that the ends of the top and bottom cleats abut the top and bottom edges, respectively, of side cleats, described below.

A pair of side cleats 40 are attached on the inside surface of each side wall panel in a parallel, longitudinally spaced relationship. The side cleats extend substantially the height of the side panels and are spaced from the top and bottom of the side panels a distance that corresponds to the thickness of the top and bottom cleats, respectively. Side cleats 40 are spaced inwardly from the edges of the side panels formed by fold lines 26 a distance which slightly exceeds the thickness of the top and bottom flaps. Preferably, the spacing corresponds to the thickness of the side cleats to permit the end of the blank to be easily fastened together and to permit the blank to be folded from a flat configuration to a boxlike configuration without deforming the flat wall surfaces of the blank due to contact with the edges of the cleats. This positioning of the side cleats also is important in avoiding excessive vertically applied shearing forces at the ends of the container when the loaded containers are stacked on top of each other. Unless the frames formed by the internal cleats are positioned near the ends of the container, these vertical shearing forces tend to cause the ends of the container to fail.

As here embodied, reinforcing flaps 50 are attached at the top and bottom of each of the side panels 22. As illustrated in FIG. 2, top flaps 28 and reinforcing flaps 50 at the top of the side panels, and bottom flap 30 and the reinforcing flaps 50 at the bottom edge of the side panels are separated by slots 42 which extend inwardly substantially to fold lines 32 and 34. The slots between flaps 28 and reinforcing flaps 50 permit adjacent flaps to be folded transversely of each other, from the position of FIG. I, to form a closed top for the container.

In the assembled container, and as illustrated in FIGS. 4 and 5, reinforcing flaps 50 are positioned outside of and overlap top flaps 28 and bottom flaps 30. Thus, these reinforcing flaps contribute to the structural rigidity of the assembled container and help seal the container.

A closure flap 52, which extends the height of one of the side panels, as illustrated in FIG. 2, is attached at one end of blank 20 to provide a convenient means for connecting one end of the blank to the other end. In the assembled container, closure flap 52 is overlapped on the edge of end wall portion 24 at the other end of blank 20 and attached to the end wall portion by staples and/or glue.

As illustrated in FIGS. 4 and 5, blank 20 is folded to provide a container including a pair of side walls formed by side panels 22, a pair of end walls formed by end panels 24, a top wall formed by top flaps 28 and top reinforcing flaps 50, and a bottom wall formed by bottom flaps 30 and reinforcing flaps attached to the bottom edge of the side panels. The top and side, and the side and bottom cleats at each end of the container are in abutting relationship and are spaced from the end of the container.

The embodiment of the invention illustrated in FIGS. 6-8 is a two-section container formed of a bottom section generally 60 which can be filled with tobacco and then compressed using either a sleeve-type of tobacco pressing apparatus or a corset-type pressing apparatus, and a top section 62 which telescopes over the bottom section.

As here embodied, and as seen in FIG. 7, top section 62 is formed of a foldable blank including two side panels 64 and two end panels 66 which alternate and are connected by fold lines 68. A closure flap 69 extends along one edge of one side panel and provides a convenient means for connecting the ends of the blank to form a boxlike open bottom section. Closure flap 69 is overlapped on the edge of the end panel 66 at the other end of the blank and attached to the end panel by staples and/or glue.

Top flaps 70 are connected by fold lines 71 to the top of end panels 66 and reinforcing flaps 72 are attached at the top of side panels 64. As illustrated in FIG. 6, top flaps 70 and reinforcing flap 72 are folded inwardly, with the top flaps positioned inside the reinforcing flaps, to form a closed top for the assembled container.

A top cleat 73 is attached on the inside surface of each top flap 70 and extends across the top flap parallel to and spaced from score lines 711, a distance which corresponds to the thickness of the end walls of bottom section 60.

As illustrated in FIG. 8 bottom section 60 is formed from a foldable blank and includes a pair of side panels 74 and a pair of end panels 75 with the end panels and side panels alternating and connected by score lines 76. Bottom flaps 78 are hingedly connected by fold lines 84 to the lower end of end panels 75, and bottom reinforcing flaps 80 are hingedly connected to the lower end of side panels 74. A closure flap 83 is provided at one end of the blank and attached to a side panel 74!.

As illustrated in FIG. 6, bottom flaps 78 and bottom reinforcing flaps are folded inwardly with the bottom flaps positioned inside the bottom reinforcing flaps, to form a closed bottom for bottom section 60 and the assembled container.

A bottom cleat 82 is attached on the inside surface of each bottom flap 78 and extends across the bottom flap parallel to and spaced from score line 84.

A pair of side cleats 85 are attached on the inside surface of each side wall 74 in a parallel, longitudinally spaced relationship. Preferably, the side cleats extend substantially the height of the side panels and are spaced slightly inwardly from the edges of the sidewalls formed by fold lines 76 to permit easy fastening of the ends of the blank together, to permit folding of the blank from a flat to a rectangular boxlike configuration, and to avoid excessive shearing forces at the ends of the container.

As illustrated in FIGS. '7 and 3, slots 86 separate top flaps 70 and reinforcing flaps 72 and slots lib separate bottom flaps 78 and the bottom reinforcing flaps 80. The slots permit adjacent flaps to be folded transversely of each other with the top and bottom flaps positioned inside the top and bottom reinforcing flaps as shown in FIG. 6.

Another embodiment of the invention is illustrated in FIGS. 9-I3 and comprises a two-section container. This container differs from the embodiment of FIGS. 68 in the placement of side cleats on the outside surface of the bottom section. This placement of the cleats in conjunction with a selection of external dimensions makes the container suitable for use with conventional corset or sleeve tobacco-pressing apparatus.

The elements of the container of FIGS. 9-13 have been designated by primed numbers which correspond to the same elements of the container of FIGS. 68. With reference to FIG. 9, it can be seen that in the assembled container of this embodiment, side cleats 85 are positioned on the outer surface of side panels 74'. This positioning of side cleats 85' is accomplished by attaching side cleats 85' on one surface of the blank forming bottom section 60, the bottom surface as shown in FIG. 11, and by attaching bottom cleats 82 on the other surface.

Four cutouts 90, illustrated in FIG. 21, are provided in bottom section 60' to permit the ends of bottom cleats 82' to project through sidewalls 74' and abut the bottom edge of side cleats 85'. Cutouts 9% are generally rectangular and have dimensions which correspond to the cross section of bottom cleats 62'. Preferably, the cutouts extend above and below the fold lines connecting side panels 74' and bottom reinforcing flaps 80.

Another difference in the container of FIGS. 9l3 is that the ends of bottom cleats 82' protrude past the edges of bottom flaps 78' a distance which corresponds to the combined thickness of a side panel 76' and a side cleat 85.

In the assembled container, illustrated in FIGS. 12 and 13, top section 62 extends downwardly to the plane of the lower surface of bottom cleats 82'. Wrapping means such as steel banding 92 is extended around the container and fastened with its ends clipped together under tension to hold top section 62 telescoped on bottom section 60. If tobacco is being packaged in the container, the wrapping means resists the tendency of the mass of tobacco to resiliently expand upwards after a pressing operation.

With reference to FIGS. 2 and 13, it can be seen that assembly of the containers of this invention provides an internal structural frame that strengthens the container and is especially effective in resisting compressive forces exerted on the exterior of the container, such as caused by stacking containers on top of each other. In each container the ends of the lower surface of each top cleat are seated on the upper edges of a pair of longitudinally aligned side cleats, and the bottom edges of the side cleats are seated in abutting contact on the top surface of the bottom cleats.

Thus, in each of the three embodiments described above, an internal three-dimensional structural frame is provided at each end of the container. These illustrated embodiments using cleats having a width to thickness ratio above 5 provide a sufficient area of contact between the frame and the fiberboard blank to prevent the blank from being sheared while at the same time providing for ease of fabrication and for a minimum storage space requirement for the disassembled container.

Fiberboard, and preferably corrugated fiberboard, forms a preferred material of construction for the wall portions of the container of the invention. The cleats used to form the structural frame can be constructed of a variety of materials which possess good compressive strength with plywood being presently preferred. lt has been found that relatively thin sheets of plywood, for example three-eighths of an inch plywood, provide sufficient reinforcement to enable fiberboard containers to be stacked without sustaining damage. lt is desirable that the cleats have a width-tothickness ratio of over five to provide a large contact area for the frames with the top and bottom of the container and to minimize the vertical dimension of the blanks in a planar knocked-down condition and thus permit storage of the disassembled containers in a minimum of space. lt is also desirable that the top, side, and bottom cleats have a uniform thickness.

Preferably, a container manufacturer prefabricates the various elements of the container which are shipped to the user in a knocked-down condition for assembly by the user to provide economical utilization of shipment and storage space. The container manufacturer would, for example, preferably score the fiberboard blanks that form the walls of the container, and attach the cleats to the wall portions of the blanks using staples and/or glue, but would not attach the ends of the foldable blanks to each other to form rectangular sections.

A preferred procedure for assembling the container of FIGS. 1-5 will now be described. Foldable blank 20. is folded from its flat condition as illustrated in FIG. 2 to form an opentopped rectangular container as shown in F IG. 1. Closure flap 52 is fastened to the free end of end panel 24 by conventional fastening means such as glue and/or staples.

As illustrated in HO. 1, the partially assembled container, can be loaded with tobacco when top flaps 28 and top reinforcing flaps 50 are folded to be positioned outside the walls 22 and 24. Preferably, a metal sleeve (not shown) is inserted adjacent the inside wall surface of the container. After piling up tobacco in a chute positioned above the container, the tobacco in the chute is compressed into the container by applying a hydraulic ram to the top of the pile of tobacco. Subsequently, the metal sleeve is removed from the container and flaps 28 are folded inwardly into a horizontal position with the ends of the lower surface of top cleats 36 seated on the top edge of side cleats 40. Top reinforcing flaps 50 are then folded inwardly into a horizontal position to form a closed top for the container.

The assembly of the containers of FIGS. 6-8 and FIGS. 9- l3 can be accomplished using similar techniques for both containers. A typical method of assembly will be described with reference to the embodiment of FIGS. 68. Initially, bottom section 60 is folded from its flat configuration shown in FIG. 8, to the open-topped rectangular box configuration illustrated in F IG. 6 and closure flap 83 is fastened to the end panel 75 at the other end of the blank. Subsequently, a metal sleeve (not shown) is inserted adjacent the walls of the bottom section to help resist bursting forces during compression of tobacco within the container. A corset could be substituted for the sleeve, and the corset would be applied around the exterior of the assembled bottom section 60.

Tobacco is loaded into a chute positioned above the opentopped container formed by the bottom section and compressed by application of a hydraulic press. Subsequently, the sleeve is removed and top section 62, which has been folded into a generally rectangular configuration, is telescoped over bottom section 60 with the side and end walls of the top section adjacent the side and end walls of the bottom section, respectively. One advantage of the two-section construction of these containers is that previously pressed tobacco, which may exhibit some resilience after release of the hydraulic press and therefore tend to rise above the top of bottom section 60, can be recompressed by exerting a downward compressive force on top section 62 to telescope it down over bottom section 60. It is usually desirable to wrap the assembled container with steel banding or the like which holds the top section in telescoped relation on bottom section 60.

This invention in its broader aspects is not limited to the specific details shown and described, but departures may be made from such details without departing from the principles of the invention and without sacrificing its chief advantages.
